The name-giving ceremony of the trailing suction hopper dredger BREYDEL took place on Friday, 16 May 2008 in the port of Ostend (Belgium). It was built for the Belgium company DEME N.V. (Dredging, Environmental and Marine Engineering N.V.). The inauguration ceremony was conducted by Mrs. Hilde Crevits, the Flemish Minister of Public Works, Energy, Environment and Nature.

IHC Dredgers BV and DEME N.V. signed the contract for the construction of two trailing suction hopper dredgers in February 2006. They were the BRABO and the BREYDEL. The keel was laid on 3 July 2007 and the BREYDEL was launched at the IHC Merwede yard in Kinderdijk (Netherlands) on 22 December 2007. After successful sea trials, the ship was delivered on 25 April 2008.

On 24 April of this year, the keel was laid for the 5,600m³ TSHD that will be built for DEME at the IHC Merwede yard in Sliedrecht. The launch is scheduled for December 2008. This ship will be a copy of the MARIEKE and REYNAERT, the successful vessels in the series that started with the PALLIETER, the BREYDEL and the BRABO. These hopper dredgers are based on the same concept, but they have a hopper capacity of approximately 10,000m³. With this investment programme, DEME has added a number of highly innovative ships to its fleet. The one-man bridge operation means they will be very competitive.

Appendix – Additional information
The BREYDEL is a twin-screw trailing suction hopper dredger, with two bow screws for optimum manoeuvrability. It has one suction pipe on the port side with an internal diameter of 1,200 mm. Maximum dredging depth is 43 m. The dredged material can be discharged directly into the sea through two rows of rectangular bottom doors. In shallow water, two front unloading doors can also be used. These are submerged bottom doors that do not protrude under the ship when opened. The load can also be discharged through a self-emptying system, in which the dredged soil is pumped ashore through a floating pipeline, or “rainbowed”, i.e. discharged through a spraying nozzle.

Jan Breydel, the resistance hero

In the early 14th century in Belgium, Jan Breydel, a butcher by trade, was the pre-eminent symbol of the growing freedom movement of the people of Bruges in the Middle Ages as they looked for ways to cast off the yoke of the nobility.
Together with Pieter de Conick, he led an uprising against Phillip IV, the Fair. This revolt, known as the Bruges Matins, led to the Battle of the Golden Spurs.
In 1309, the celebrated duo was joined by Jan Heem in the revolt in Bruges against the Athis-sur-Orge peace treaty (1305).
A statue of Jan Breydel and Pieter de Conick has decorated the Market Square in Bruges since 1887. Jan Breydel has remained celebrated for his passionate championship of the Flemish identity until the present day.

Trailing suction hopper dredger
A dredger used to remove and transport soil from water beds by dragging a long suction tube (2) with a draghead (1) over the bed, loosening the soil in front of the suction head. The material is stored in the hopper (3), which is then discharged through the bottom doors (4), pumped through a floating pipeline, or ‘rainbowed’ (i.e. discharged through the jet nozzle (5) to a reclamation area.

Specific activities in this field include the construction or deepening of harbours and waterways. The main advantages of this type of vessel are its relative immunity to weather and sea conditions and the ability to transport material over long distances. Furthermore, it can operate independently with hardly any interference to other shipping traffic.
